Rationale and Objectives. To find signs in vector-electrocardiography (VECG) predicting the ventricular fibrillatory propensity (VF-PROP) of iodixanol and mannitol solutions after injection into the left coronary artery (LCA) of pigs. Materials and Methods. Five plasma-isotonic solutions perfused LCA: lod 320 + Na/Ca (iodixanol 320 mg I/mL, 19 mM NaCl, 0.3 mM CaCl2), lod 320 + Mann (iodixanol 320

A folder in the Ericsberg archive contains a rare collection of small ephemera printed to be used as theatre posters, advertisements for fanciful shops, pharmaceutical labels on imaginary medicines, lottery tickets etc. at a 1749 christmas party at the court of Queen Lovisa Ulrika of Sweden. The festivity was organized as a street market inside the palace by the Chancellor Count Tessin, and the te

The glacial unloading and resulting isostatic land uplift have together with hydro-isostasy, eustatic rise of sea-level and geoidal changes, ruled the shore displacement of Fennoscandia. Within the Baltic basin, periods of damming and shifts of outlet further complicated the shore displacement during the period studied, c. 12,200-8400 BP. Information on the Baltic history was derived from shorelin

We investigate the effects of adaptive time-stepping and other algorithmic strategies on the computational stability of ODE codes. We show that carefully designed adaptive algorithms have a most significant impact on computational stability and reliability. A series of computational experiments with the standard implementation of Dassl and a modified version, including stepsize control based on di

The influence of the cranial sympathetic nerves on the architecture of pial arteries in normo- and hypertension was examined. For this purpose the effect of bilateral superior cervical ganglionectomy was evaluated in normotensive rats (WKY) and stroke-prone spontaneously hypertensive rats (SHRSP). The operations were performed at the age of 1 wk, which is just prior to the onset of ganglionic tran

Objective: To investigate whether determination of a set of laboratory markers at baseline provides prognostic information on joint damage in hands and feet in rheumatoid arthritis. Methods: 183 patients with early rheumatoid arthritis included in a prospective study were examined. Radiographic changes in hands and feet at 5 and 10 years after inclusion were evaluated (Larsen). The markers analyse

The report gives a summary of Björn Wittenmark's visits to China and Australia during the academic year1986 /87 . An overview of the research is given together with a summary of impressions during visits at differentuniversities.

BACKGROUND: Immunohistochemical staining for tumor-associated proteins is widely used for the identification of novel prognostic markers. Recently, a tissue-conserving, high-throughput technique, tissue microarray, has been introduced. This technique uses 0.6-mm tissue core biopsy specimens, 500 to 1000 of which are brought into a new paraffin array block, which can be sectioned up to 100 times. M

GABA is the main inhibitory neurotransmitter in the mammalian CNS. GABA in the brain is commonly associated with a fast, point-to-point form of signalling called synaptic transmission (phasic inhibition), but there is growing evidence that GABA participates in another, slower and more diffuse form of signalling often referred to as tonic inhibition. Unresolved questions regarding tonic neuronal in

Popular Abstract in Swedish Även om vi kanske inte tänker på det så ofta så är vår förmåga att bedöma likhet av stor vikt, inte minst då det gäller begreppsbildning och generalisering. Denna avhandling handlar om likhet, speciellt geometriska modeller av likhet. I sådana modeller representeras objekt som punkter i abstrakta rum, och likhet svarar (omvänt) mot avstånd i rummen. Avhandlingen tar uThis dissertation examines and discusses some phenomena related to the geometric representation of similarity. It takes its inspiration from the existing body of empirical research within the fields of perceptual and cognitive psychology, but also connects to certain areas of machine learning. The problems discussed concern the modelling of information integration behavior when concepts like asym

En kritisk genomgång av svensk och internationell litteratur kring innemiljöns påverkan på människans hälsa - det område som på engelska sammanfattas under begreppen SBS (Sick building syndrome) och IAQ (Indoor air quality).

Long term follow up of 16 homosexual men and 78 intravenous drug abusers who were chronic carriers of hepatitis B surface antigen (HBsAg) showed fundamental differences between the two groups. Viral replication, expressed by the presence of hepatitis B e antigen, lasted for four years or more in 10 out of 14 (71%) of the homosexual men whereas it was not present in 43 out of 73 (59%) of the drug a

Objective: Explore the long-term course of schizophrenia and related disorders. Method: Naturalistic study of 225 patients initially treated with risperidone (monotherapy or in combination with other psychotropic drugs) over 5 years. Results: Stable symptomatology and side effects were observed. Clinician GAF scores were 55-61, but patients' self-ratings were higher. Clinician and patient CGI scor

Background: Different screening procedures are becoming an important part of health care. information about screening and its consequences can be difficult to both impart and understand. This study examined women's theoretical acceptance of a new screening procedure, before its introduction. Methods: A group of women (n = 823), who had made an informed choice about the form of foetal diagnosis the
